Dau’d (or Dawud) is the Arabic form of “David” and anyone referred to as a “prophet of Islam” is someone that came before Mahomet, so this is a reference to King David of Israel, who of course was no “prophet of Islam” any more than Abraham (Ibrahim) or Moses (Musa) was.

The point is that Muslims CLAIM David as one of their prophets, not that it is necessarily a legitimate claim. Pointing out the Arab equivalent of the name "David" is useful, however.
